Aeration for wastewater treatment is the process of adding air into wastewater to allow the aerobic biodegradation of the pollutant component.
It is an essential part of many biological wastewater treatment systems. It is different from chemical treatment as it uses chemicals to react and alleviate impurities in wastewater flow. You can also opt for advanced aerated water treatment system.
When Is Aeration Used And How It Works?
In the processing of industrial and municipal wastewater, aeration is the part of the secondary treatment process. The activated sludge process is the most common choice in the secondary process.
Aeration in the activated sludge process is filling air into the tank, which helps in the growth of microbes in the wastewater.
Aeration provides oxygen to the bacteria to treat and stabilize wastewater. Oxygen is needed by bacteria to enable biodegradation occurs.
Supplied oxygen is used by bacteria in the wastewater to break down organic materials containing carbon to form carbon dioxide and water.
Without the presence of sufficient oxygen, the bacteria cannot decompose organic matter included in a reasonable time. In the absence of dissolved oxygen, degradation should occur in septic conditions slow, odorless, and produces a complete conversion of pollutants.
Why It Is Important For Wastewater Treatment?
Aeration is the most important component of the treatment system using an activated sludge process. A well-designed aeration system has a direct impact on the level of wastewater treatment was reached.
